Game Center has just gone live for anyone with iOS4.1 on their device, as promised by Apple at it’s Fall music event. Up until this point users, primarily developers, have been using a sandboxed version of Game Center that allowed you to find friends only via username. Users can now create a full blown Game Center account, pick their gamer tag and verify as many email addresses as they want, so that people can find them via email and allowing you to send invites to friends via email, something that up until just now was not possible.

Here’s some screens from an iPhone 4 to tide you over till iOS4.1 officially launches (probably tomorrow).
